Gas in early-type galaxies: cross-fuelling in late-type-early-type pairs?
Cullen, H.; Alexander, P.; Clemens, M.
Abstract. We present^12^CO (J= 1-0) and^12^CO (J= 2-1) observations of
eight early-type galaxies, forming part of a sample of interacting
galaxies, each consisting of one late- and one early-type system. All of
the early-type galaxies observed are undetected in CO to low levels,
allowing us to place tight constraints on their molecular gas content.
Additionally, we present HI absorption data for one system. The
implications for possible gas transfer from the late- to the early-type
galaxy during the interaction are discussed.
